Rage Hypo 2 100gr Expandable Broadhead - The Hypo 2 is an improved Shock Collar version of the original Hypodermic Series of Slip Cam Broadheads, featuring a triangular keyed shock collar that only allows the Shock Collar to be installed in the correct orientation to eliminate improper installation. Once in place, the tried-and-true Shock Collar blade locking system holds the two razor-sharp stainless-steel blades closed until impact. Upon impact, the blades instantly deploy to a 2+ inch cutting diameter, administering the gaping wounds that bowhunters have come to expect from the field-proven Rage Hypodermic series. The keyed Shock Collar also allows for all 6 pedals to be used; simply remove the collar, spin 120 degrees and reinstall. The Hypo 2 features an even sharper Hypodermic hybrid tip and more swept blade angle for increased penetration. In flight, that streamlined design makes for superior field-tip accuracy.
